Kernel-4.18.0-80.el8_hisilicon-hip04-net

Hisilicon hip04 Ethernet Controller

• Ethernet controller node

Required properties:

• compatible: should be “hisilicon,hip04-mac”.
• reg: address and length of the register set for the device.
• interrupts: interrupt for the device.
• port-handle:
  phandle, specifies a reference to the syscon ppe node
  port, port number connected to the controller
  channel, recv channel start from channel * number (RX_DESC_NUM)
• phy-mode: see ethernet.txt [1].

Optional properties:

• phy-handle: see ethernet.txt [1].

[1] Documentation/devicetree/bindings/net/ethernet.txt

• Ethernet ppe node:
  Control rx & tx fifos of all ethernet controllers.
  Have 2048 recv channels shared by all ethernet controllers, only if no overlap.
  Each controller’s recv channel start from channel * number (RX_DESC_NUM).

Required properties:

• compatible: “hisilicon,hip04-ppe”, “syscon”.
• reg: address and length of the register set for the device.

• MDIO bus node:

Required properties:

• compatible: should be “hisilicon,mdio”.
• Inherits from MDIO bus node binding [2]
